在SpringBoot項(xiàng)目中，使用thymeleaf模板中使用th:onclick來(lái)調(diào)用javascript方法時(shí)異常。異常信息如下：

Caused by: org.attoparser.ParseException: Only variable expressions returning numbers or booleans are allowed in this context, any other datatypes are not trusted in the context of this expression, including Strings or any other object that could be rendered as a text literal. A typical case is HTML attributes for event handlers (e.g. "onload"), in which textual data from variables should better be output to "data-*" attributes and then read from the event handler.
